This visualization shows Earth’s axial precession, a wobble in the planet’s rotational axis with a period of about 26,000 years that is induced by tidal forces from the sun and moon.

With axial precession being a scientific fact, why doesn’t tropical astrology factor it into its system? Well, in all honesty, precession makes things complicated.

When updates were made to Shi Shi Xing Jing by Han Dynasty astronomer Zhang Heng sometime around 125 A.D., axial precession meant that star positions were inconsistent with Shi’s original catalog.
